Fig. 6From: In situ synthesis of silver nanoparticles on the surface of PDMS with high antibacterial activity and biosafety toward an implantable medical deviceElectron microscopic analysis of the AgNP-grown PDMS films subjected to various rounds of reactions. From a to c; one, two and three rounds of reaction, respectively. d Ion mapping image and inset of d corresponding electron microscopic images of AgNP-grown PDMS films after three rounds of the AgNP growing reaction. Insets in b and c are enlarged images of the figures. 500 nm scale bar in each SEM imageBack to article page
